Following the theme of everyone else, go vote today.

Update:
One small observation from my polling place this morning: Unless you are personally willing to volunteer as a poll worker, don’t complain that things are moving slowly. In my particular precinct, we’ve had a good sized population increase in the last four years, but no one is ever sure of how good turn out will be until the day comes. So, preparing for the rush of voters before work, at lunch, etc is hard to do. 40 minutes out of this one day seems pretty small compared to the impact it could have over the next 4 years.
Also, if you are unsure of your polling place, you should have looked before today, but if you didn’t don’t get mad at the volunteer for sending you someplace else.

I’m still mulling over some other observations, but for now, that is all.
